Análisis comparativo del servicio de streaming de video de youtube entre las operadoras de datos móviles 4G en el Ecuador, para proponer parámetros mínimos de calidad.

Abstract

It was conducted a comparative analysis of the service of streaming of video of You Tube on the networks of 4G mobile data in Ecuador. In order to make the comparison, statistical tools were used on data collected in the field by means of measurements carried out in Cuenca city, Ecuador, into a fixed outdoor environment. For the measurements, it was used the technological tool "Tems pocket" belonging to "Info Vista" company, equipment that the Agency of Regulation and Control of Telecommunications (ARCOTEL) owns. This institution is the place where this research was carried out. In addition to this, a proposal for the use of the "Pocket Tems" tool for future measurements was developed. The comparative analysis was done according to the Key Performance Indicators (KPI), both for Quality of Service (QoS) and quality of experience (QoE). The quality of experience (QoE) was measured by means of the KPI "Average Video Quality" with the use of the PVQ-s standard, on a MOS scale. In the investigation it was determined with statistical tests that the KPI "Average Video Quality", in the three mobile operators, came from populations of identical behaviour, therefore with equal distributions. Finally, with the collected results, minimum parameters, or service quality objectives are proposed for the analysed KPIs, which are: "Video Play Start Time" ≤1.3 seconds, "Service Access Time" ≤ 0.3, seconds "Reproduction Start Delay " ≤ 1 second, and “Average Video Quality" with MOS ≥ 4.
